<h2>Answer:</h2>

Option: C is the correct answer.

            C.  a_n=a_{n-1}-3\ ;\ a_1=2

<h2>Step-by-step explanation:</h2>

The sequence is given by the explicit formula as:

a_n=5-3n

where a_n is the nth term of the sequence.

Also, the first term of the sequence is: a_1

i.e.

a_1=5-3\times 1\\\\i.e.\\\\a_1=5-3\\\\i.e.\\\\a_1=2

Also,

a_n=5-3n\\\\i.e.\\\\a_n=5-3n+3-3\\\\i.e.\\\\a_n=5-3(n-1)-3\\\\i.e.\\\\a_n=a_{n-1}-3

   Hence, the recursive formula which represents the same sequence is:

A bottle fruit juice holds 1.89L. If shakira bought almost 6L of fruit juice, how many bottles did she buy
anyanavicka [17]
Since the question is asking how many bottles Shakira bought that was ALMOST 6L, she bought about 3 bottles.

6.00 / 1.89= 3.17460317= 3.175
Liters/ Bottle of Juice Amount

To check your work, multiply 3.175 by 1.89, you’d get 6.00075, about 6L.

The question is asking ALMOST, so it can’t be exact, so uyour answer would instead be 3.
3• 1.89=5.67L
